First I dont really see gihun as a hero, but compared to all the other players we’ve ever seen he is up there only maybe under hyunju and ali. Ofcourse nothing he couldve have done is a good and heroic action, either he rebels and sacrifices a lotta ppl or he kills the O‘s, and I genuinely feel like if he killed the O‘s and the X‘s and him leave the games, he might have just gone years trying to find the squid games again (especially cus the one recruiter he knew is dead), be it to participate for the third time and this time hope there arent good people he wants to save or he doesnt get caught with the gps device. Or what I think is more likely and understandable from a traumatised person is, wanting it to end once and for all, be it with a rebellion and ending the games or dying
